Every payment, every login, every confidential file sent across India today is locked with mathematics that works beautifully — against the computers of today. A sufficiently powerful quantum computer, the kind researchers around the world are racing to build, could one day pick those locks open. And the encrypted data being harvested and stored right now would be waiting for it. A Chennai company called YesPanchi has decided India should not wait to find out: its new product, QSecura – PQSSL, wraps the internet’s everyday security layer in cryptography designed to survive the quantum era.
QSecura – PQSSL is a post-quantum SSL/TLS layer for websites, web applications and mobile platforms, launched by YesPanchi Tech Services in November 2026. It strengthens data in transit — the information flowing between a user’s phone or browser and a company’s servers — with post-quantum cryptography, so organisations can begin the move to quantum-safe security now, while their existing systems keep running exactly as before.
A new lock for an old problem
The threat QSecura is built for has a name that says it all: “harvest now, decrypt later.” Encrypted traffic intercepted today can be stored cheaply and decrypted years from now, once quantum computers are powerful enough to break today’s public-key cryptography. For information that must stay secret for years — financial records, health data, government communications — that makes the migration to quantum-safe encryption a job to start now, not when the first cryptographically relevant quantum computer arrives.
QSecura approaches that migration the practical way. It works as a layered security architecture that sits alongside the HTTPS protections organisations already rely on, introducing quantum-safe mechanisms where they fit rather than demanding a rip-and-replace of working infrastructure. The company says the product is already being implemented in select FinTech applications, putting quantum-safe protection into live payment environments.
Built on the standards the world is moving to
Under the hood, QSecura is built around the post-quantum algorithms standardised by the US National Institute of Standards and Technology: ML-KEM for key exchange, ML-DSA and SLH-DSA for digital signatures, running over TLS 1.3. The design pairs those new algorithms with classical cryptography in hybrid combinations, so a connection stays protected even while the industry’s standards keep evolving.

That flexibility is the point. QSecura is designed for crypto-agility — the ability to swap cryptographic algorithms as standards change, without rebuilding the application — and for a staged migration journey: discover what cryptography an organisation depends on, assess the risk, pilot the new layer, migrate, and operate. The company says the platform covers post-quantum SSL/TLS security, protection of sensitive data in transit, readiness assessments, harvest-now-decrypt-later risk mitigation and integration with existing enterprise infrastructure.
Why the timing matters
QSecura arrives just as India’s financial system is being told, from the top, to get ready. At the Global FinTech Fest 2026, the Reserve Bank of India called on payment operators to begin preparing their systems for the quantum era, and the central bank has set up its Quantum Secure and Adaptive Financial Ecosystem (Q-SAFE) committee to map the sector’s cryptographic inventory and chart a quantum-security roadmap. A Department of Science and Technology task force has recommended that critical information infrastructure establish its quantum-security foundations by 2027, migrate high-priority systems by 2028 and complete post-quantum adoption by 2029 — all under the National Quantum Mission, the Rs 6,003.65-crore programme approved in 2023.
YesPanchi is working inside that national push. In August 2026 the company signed a memorandum of understanding with the IITM C-DOT Samgnya Technologies Foundation, the IIT Madras and C-DOT-backed foundation, to collaborate on quantum technologies, cybersecurity, research, innovation and capacity building. QSecura sits alongside the company’s earlier quantum product, Quantik, a quantum-safe encryption and key-exchange platform for financial networks.
The team behind the shield
YesPanchi Tech Services was founded in Chennai in June 2021 by Panchi Subramanian, a technology entrepreneur and PayTech security expert with almost three decades in technology and financial services. She is the organising secretary of the Digital Security Association of India, and the company she leads is a government-recognised MSME startup backed by Startup India, operating from the IIT Madras Research Park in Tharamani.
The company’s work spans cybersecurity, artificial intelligence, enterprise AI platforms and digital transformation, with products including UNIFAI, an enterprise AI operating layer, BoardMind for boardroom governance and Alexi Voice for conversational AI. Subramanian’s leadership has been recognised with honours including Professional of the Year 2021 from the MSME India Forum, Woman Business Leader of the Year 2021, a place among the FICCI–TNIE Startup Stars, and Visionary Woman Leader 2023 from Redington, Microsoft and Check Point.
For India’s banks, payment companies and enterprises, the question QSecura poses is deliberately simple: your application is protected by SSL today — but is it prepared for the quantum era? With a made-in-India answer now in live FinTech deployments, the country’s move from quantum awareness to quantum readiness has a homegrown product leading the way.
